"Step into the void" in Chamonix

It’s an invitation that’s not for the fainthearted: 'Step into the Void' is the name of a transparent glass cube that simulates the sensation of stepping off the mountain cliff in the French Alps.

Located atop the Aiguille du Midi in the Mont Blanc Massif range, with an altitude of 3,842 meters, daredevils step into the glass box “Pas dans le Vide” suspended more than 1,000 meters off the valley floor for an unparalleled panoramic view of their snowy surroundings.

Three years in the making, the structure is built from three layers of tempered glass and can withstand winds of more than 220 km/h and a maximum temperature of 60°. The attraction is accessible by the Aiguille du Midi cable car, a 20-minute journey from Chamonix.

It’s the latest glass-covered attraction to take visitors to new heights, following the Skywalk, a glass walkway overlooking the Grand Canyon, and the CN Tower in Toronto, which features a glass-bottom floor 1,122 m above ground.
